The bolivar, like Venezuelaâs economy, is trapped in a downward spiral. Within Venezuela the effects of the economic chaos are seen at the supermarket, where empty shelves are a constant reminder of the economic dysfunction that has come to define South Americaâs fifth largest economy.
In optics, chromatic aberration (CA, also called achromatism, chromatic distortion, and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.n some circumstances it is possible to correct some of the effects of chromatic aberration in digital post-processing. However, in real-world circumstances, chromatic aberration results in permanent loss of some image detail.
Limitations of Refracting Telescopes. Lenses create a type of image distortion known as chromatic aberration. This occurs because as light passes through a lens, different colors are bent through different angles (like in a prism) and brought to a focus at different points.
